• TightVNC (or any VNC) viewer windows scaling

  - by mr.b

  Hi, I am currently using TightVNC to connect to multiple remote hosts in LAN. I start 16 VNC viewers, set Scaling by: Auto (in connection options display), and then select all viewer windows and use Tile Horizontally, which covers my entire screen with VNC viewers. It all works sort of nice, except that desktop interaction is really slow when there are more then 4 VNC viewers. My question is, does VNC client (not just TightVNC, but any compatible client) support some kind of smart scaling option, so that client tells server something along the lines of: "Okay, I'm displaying your entire screen in a window size 300x225 px, so can you please start sending encoded images on that resolution?", at which point interactiveness of open connections dramatically increase, and when I decide to go full screen on some connection, client and server re-negotiate and server starts sending full resolution images again? Thanks!!

• Website deployment - managing uploaded content?

  - by Legion

  I'm a programmer by trade, "server administrator" by company necessity. We're looking at dumping the old painful "update site by FTP upload" style of deployment. Having the webserver check out the latest code base from version control into a folder and having a "current" symlink point to the latest checkout (allowing for easily stepping back to an older version by changing the symlink) seems to be the way we want to go. But I have a question: what's a good practice for dealing with user-uploaded content? This stuff isn't in version control. I have a couple of ideas for dealing with this, but what is the smart, accepted practice?

• Video/Animated GIF advanced frame editor?

  - by meder

  What sort of application could I use for example if I had a 5 minute video or an animated GIF with 50 frames, and I wanted to basically Photoshop replace an object, say a person's head, with another image for all those 50 frames? Is there some sort of smart tool that can do this or do I have to edit every single frame by hand? I wouldn't mind there being a tool where I can paste the image in every frame automatically, and switch from frame to frame adjusting the position of it, I just need something efficient. I've tried using Photoshop's import video into image sequence and tried editing with the animation toolbar at the bottom, but it's not quite what I want. I don't care if it's free software or not, I'm primarily using Linux but I have VirtualBox Windows XP if there's an excellent application that's not available otherwise.

• HP Server bios boot delay

  - by jjrab

  I'm just going to throw this out there in case anyone else has run accross this... I have an HP DL320 G5p that had the motherboard replaced due to a faulty NIC port. After several calls to HP, two motherboard replacements, PCI riser card replacements, Processor replacement, and power supply replacement, the server takes approx. 10 minutes before it boots into the BIOS. It then boots up with no issues. We've run the HP smart start cd and performed the system tests and everything passed. All firmware has also been upgraded to the latest as well. Has anyone else seen this and found a fix? I am still working with HP, but there seems to be a struggle on their part to figure this out, so I'm curious to know if anyone else has experienced this and found a fix - thanks...

• Join .doc files into one .doc (with keeping the original format of every document)

  - by Shiki

  I have about ~50 .doc files, that look perfect (they are extracted with Able2Extract). Now I want to join these 50 files into one huge .doc. I've tried using Word's in-built "Insert" feature, but that messed up the whole format. I want to keep everything I have. Like just document1 - document2 - document3. Nothing "intelligent" or "smart" needed during the conversion, just the capability of joining them. (Thus making them all searchable, that's the ultimate aim.) I don't mind if the method/solution applies a single blank page at every document end either.

• Just one client bound to address and port: does it make a difference broadcast versus unicast in terms of overhead?

  - by chrisapotek

  Scenario: I am implementing failed over for a network node, so my idea is to make the master node listens on a broadcast ip address and port. If the master node fails, another failover node will start listening on this broadcast address (and port) and take over. Question: My concern is that I will be using a broadcast IP address just for a single node: the master. The failover node only binds if the master fails, in other words, almost never. In terms of network/traffic overhead, is it bad to talk to a single node through a broadcast address or the network somehow is smart enough to know that nobody else is listening to this broadcast address and kind of treat it as a unicast in terms of overhead? My concern is that I will be flooding my network with packets from this broadcast address even thought I am just really talking to a single node (the master). But I can't use unicast because the failover node has to be able to pick up the master stream quickly and transparently in case it fails.

• What are the limitations of virtual machines?

  - by j-g-faustus

  I'm considering setting up a virtual machine running Windows, with Ubuntu 10.10 as the host OS, for those cases where I have a Windows-only program. I understand that using a VM will lose some performance, but are there other limitations to what the OS in a virtual machine can do compared to "running on bare metal"? For example: Can a VM play games, like Dragon Age Origins or Civilization V? (Possibly with poorer framerates and/or lower resolution, but does it play at all?) Can a VM rip DVD/Blue-ray using AnyDVD or similar Windows program? Can a VM handle new hardware that requires dedicated drivers, but the drivers are only available for the OS running inside the VM? (Ex. graphics card, digital camera, card reader for smart card authentication.) Is it possible to say anything about "general limitations" of VMs, or is this wholly dependent on the specific VM?

• Linear Performance Scalability with HP San Solutions

  - by Berzemus

  Hi all, I need a San Solution with linear scalability in size as well as in performance. From what I know, with a Modular Smart Array solution such as the P2000/MSA-class solutions from HP, even with a dual controller initial node, I can only increase the size of it, as added nodes come controller-less, so overall performance tends to decrease. On the other hand, the P4000 (lefthand) family of solutions has each of it's nodes have it's own controller, and so when a node is added, storage capacity as well as performance increase. Am I right in all that I say, and is the P4000 the only solution, or have I forgotten something ?

• ZFS SAS/SATA controller recommendations

  - by ewwhite

  I've been working with OpenSolaris and ZFS for 6 months, primarily on a Sun Fire x4540 and standard Dell and HP hardware. One downside to standard Perc and HP Smart Array controllers is that they do not have a true "passthrough" JBOD mode to present individual disks to ZFS. One can configure multiple RAID 0 arrays and get them working in ZFS, but it impacts hotswap capabilities (thus requiring a reboot upon disk failure/replacement). I'm curious as to what SAS/SATA controllers are recommended for home-brewed ZFS JBODs. In addition, how does battery-backed write cache (BBWC) play into the solution?

• Filter MP3s by encoder type?

  - by Brandon

  I'm on a Mac and use iTunes to manage my music collection. I'm in the process of weeding out the lower quality files that I have and would like to have only MP3s that have been encoded using the V0 setting of the LAME MP3 encoder. I tried using iTunes' smart playlist feature but as it only allows a less than rule and V0 is a variable amount, it catches valid V0 encoded files a lot of the time. Is there any alternative program on Mac that I can just point to my iTunes folder and say, "show me all files that are not encoded with LAME V0"?

• What tools can be used to download all images in a webpage?

  - by bobo

  I would like to download all images in a web page. The tool should be smart enough to examine the css and javascript files in the page source to look for the images. Ideally, it should also replicate the folder hierarchy, saving the images in the correct folder. For example, the web page may have some images for menu items stored in images/menu/ and for background images it may be stored in images/bg/. Is there such a tool that you know of? (preferably in Windows but Linux is still ok) Many thanks to you all.

• Problem setting up DL360G5 with scsi RAID

  - by ernelli

  I have a problem with reinstalling OS on a DL360G5. The BIOS [F9] do not detect any disc controllers and the HP SmartSetup did not find any compatible controllers. Inside the server, the two SCSI disks are conncted to a RAID controller using BCM8603 chipset. How is disc contoller supposed to be setup? I have tried to do a full BIOS reset. EDIT At the moment we suspect that the Smart Array controller E200i/412205-001 is broken. Are there any status LED's that indicate failure or success during start up? At the moment all LED's are off.

• Windows XP Home Edition SP3 cant recognise PCMIA SD Card

  - by Pozo

  System Specifications: Laptop : Dell Inspiron 6000 OS: Windows Home Edition SP3 SD Adapter: Hagiwara Smart Media Adapter I inserted the card into the slot, windows xp recognises the device, lists the pcmia controller on the device manager list, an entry appears under the IDE ATA/ATAPI category on the device manager as well. However, the device does not show under my computer and the driver does not get assigned a letter number. I checked the system logs from the device manager and there were no logged errors. Checking the Hagiwara support website, the manufacturer indicates that the adapter driver is the same as the windows xp pcmia controller. Checking Dell's website, no specific drivers were listed for that either. General Search on the web indicates that multiple people face similar problems with their SD cards, yet none actually spell out the route issue that causes this. Please let me know if you have any suggestions for further debugging. Thanks in advance

• How much memory should my rails stack be consuming?

  I am running my own webserver on a 384MB VPS from Slicehost to serve two Ruby on Rails applications on separate Virtual Hosts. I am running Phusion Passenger with Apache2. The following is the contents of my Passenger.conf <IfModule passenger_module> PassengerRoot /opt/ruby-enterprise-1.8.6-20090610/lib/ruby/gems/1.8/gems/passenger-2.2.11 PassengerLogLevel 0 PassengerRuby /usr/local/bin/ruby PassengerUserSwitching on PassengerDefaultUser nobody PassengerMaxPoolSize 3 PassengerMaxInstancesPerApp 2 PassengerPoolIdleTime 300 # Ruby on Rails Options RailsAutoDetect on RailsSpawnMethod smart NameVirtualHost *:80 If i do a 'top' on my server I have 314MB used on average, this seems like too much? Am I mistaken and if not what possible steps can I take to reduce the Memory usage? Thanks!

• HP DL380 G5 Predictive Drive Failure on a new drive

  - by CharlieJ

  Consolidated Error Report: Controller: Smart Array P400 in slot 3 Device: Physical Drive 1I:1:1 Message: Predictive failure. We have an HP DL380 G5 server with two 72GB 15k SAS drives configured in RAID1. A couple weeks ago, the server reported a drive failure on Drive 1. We replaced the drive with a brand new HDD -- same spares number. A few days ago, the server started reporting a predictive drive failure on the new drive, in the same bay. Is it likely the new drive is bad... or more likely we have a bay failure problem? This is a production server, so any advice would be appreciated. I have another spare drive, so I can hot swap it if this is a fluke and new drive is just bad. THANKS! CharlieJ

• prevent OS X from prompting disk initialization/formatting

  - by Just-A-User.A-Superuser

  i have TrueCrypt partition, when i insert it in OS X, it always prompt me to initialize the hard disk. is there a way to prevent os x from detecting uninitialize hard disk? [UPDATE] by the way, as Truecrypt suggested while i'm in Windows, i must make partitions so the os won't detect the hard drive as uninitialized. Windows respected that the drive already have contents by the mere fact that it has partitions, while OS X thinks that it is still uninitialized. i think OS X is trying to be smart by detecting if each partition has a valid filesystem id/marker

• Are Snow Leopard text substitutions scriptable?

  - by yonatron

  I prefer using typographical quotation marks when possible, so I love the Smart Quotes part of Snow Leopard’s text replacement feature. But there are a few cases in which I need to toggle it, and it’s a pain to do so from the contextual menu when I’m typing. Is there any way (preferably via AppleScript, but I can deal with other suggestions) to toggle specific types of text replacement for the frontmost text-input control? And if so, what’s a good way to assign it to a globally-accessible keyboard shortcut (via 3rd-party app if necessary)?

• Configuring BIND to use VM's DNS for specific domain

  - by Srirangan

  I work on a project for which I use an Ubuntu server vm on an Ubuntu host. The VM runs all the services / webapps through haproxy and nginx and serves it on the domain (xyz.com). I manually modify my resolv.conf to use the VMs IP address as the nameserver and I can run my app on the host browser. The problem is I am modifying an auto-generated file (resolv.conf) and I need to do it each time. Is there a smart way to say: -- are you accessing xyz.com? -- if yes use VM's DNS server, else use the hosts

• Need advice to choose correct wi-fi drivers for Dell Vostro 3560

  - by overdriven

  I'm having problems with my Dell notebook's Wi-Fi, it can't see some of the available access points, despite they are close and I used to be connected to them yesterday. Other notebooks and my phone can see them. I believe it's a driver issue, since after installing system I haven't downloaded any network drivers. I went to Dell's website to search for them but I have no idea which should I choose. For my Dell Vostro 3560 and system Windows 8.1 64bit these are available: Intel Smart Connect Technology Application APP_iSCT_W8.1_A00_Setup-TJW84_ZPE.exe (23 MB) Vostro-3560_Network_Application_TJW84_WN_4.2.40.2418_A00.EXE (29 MB) Dell Wireless 1704 WLAN 802.11b/g/n (2.4GHz), Bluetooth v4.0+HS Driver DW1704_W8.1_A00_Setup-K1HGN_ZPE.exe (239 MB) Network_Driver_K1HGN_WN_6.30.223.143_A00.EXE (247 MB) Dell Wireless1703 802.11 b/g/n, BT4.0 + HS Driver Dell Wireless1901 802.11a/b/g/n (2.4GHz and 5GHz), Bluetooth v4.0+HS Driver DW1703_DW1901_Win8.1_A00_Setup-7FPWR_ZPE.exe (265 MB) Network_Driver_7FPWR_WN_10.0.0.263_A00.EXE (272 MB) Realtek RTL8105E/RTL8111E Ethernet Controller Driver LOM_Realtek_W8.1_A00_Setup-0XCVW_ZPE.exe (6 MB) Network_Driver_0XCVW_WN_8.018.0621.2013_A00.EXE (12 MB) Intel® Centrino® Wireless-N 2230 Bluetooth Driver BT_Intel_W8.14_A00_Setup-XR83W_ZPE.exe (31 MB) Network_Application_XR83W_WN_3.1.1307.0362_A00.EXE (37 MB)

• Automatic switching between "digital output" (HDMI) and built-in speakers in Vista

  - by Laurence Gonsalves

  We occasionally connect my wife's laptop, which runs Vista, to our TV. Whenever we do this we have to manually switch the default audio output to "digital output" for the sound to go through the HDMI connection, and we also have to restart any apps that we want to send sound to the TV. We then have to perform a similar process when disconnecting. Is there any way to just have this be automatic? It seems absurd to have to do so much manual fiddling when a 40 year old transistor radio is "smart" enough to turn off the speakers and send sound to the headphones when headphones are plugged in. In case it helps, the name "RealTek" shows up in the sound card settings dialog.

• Do I really need twho different Exchange servers 2007|2010?

  - by lrosa

  Given am Exchange Server 2003 running on a dedicated server on a LAN protected by a Linux in DMZ, Microsoft says that if you upgrade, you should install two different servers (meaning two boxes, two licenses of Windows Server and two installations of Exchange) with different Exchange "server role". Exchange is installed in a safe LAN, there is a Linux relay in DMZ that feeds messages to Exchanges and gets from it the messaged to be delivered on the Net (smart relay). The mail traffic is about 2000 Internet messages/day and probably another 2000 msg/day sent by local users within the organization. The servers hosts 200 users.

• perfmon reporting higher IOPs than possible?

  - by BlueToast

  We created a monitoring report for IOPs on performance counters using Disk reads/sec and Disk writes/sec on four servers (physical boxes, no virtualization) that have 4x 15k 146GB SAS drives in RAID10 per server, set to check and record data every 1 second, and logged for 24 hours before stopping reports. These are the results we got: Server1 Maximum disk reads/sec: 4249.437 Maximum disk writes/sec: 4178.946 Server2 Maximum disk reads/sec: 2550.140 Maximum disk writes/sec: 5177.821 Server3 Maximum disk reads/sec: 1903.300 Maximum disk writes/sec: 5299.036 Server4 Maximum disk reads/sec: 8453.572 Maximum disk writes/sec: 11584.653 The average disk reads and writes per second were generally low. I.e. for one particular server it was like average 33 writes/sec, but when monitoring in real-time it would often spike up to several hundreds and also sometimes into the thousands. Could someone explain to me why these numbers are significantly higher than theoretical calculations assuming each drive can do 180 IOPs? Additional details (RAID card): HP Smart Array P410i, Total cache size of 1GB, Write cache is disabled, Array accelerator cache ratio is 25% read and 75% write

• File corruption when copying different file on raid 1

  - by Stephan

  I have a RAID 1 configuration of 2 1TB drives on a Fedora 12 box. Most of what is stored there are video files that are numerical labeled. The problem I'm having is that I had one of the video files get corrupted. I copied a replacement from a backup and replaced the bad file and now it works fine. However, after doing this the next numbered file goes from 350MB to 200KB and all but about .5 second of video disappears. If I then replace that file it happens to the next one down the line. Ex: Replace corrupt file 1.avi and file 2.avi shrinks to 200KB. Replace now corrupted 2.avi and it works but 3.avi gets screwed up. I have run SMART tests on the drives and they report fine. Does anyone have any tests I can run to try to figure out what is going on? EDIT: It is a two disk software RAID 1 with an ext4 filesystem
